The eye nebulizer deploys at least a block piece along a tube for the nebulized medication so as to achieve an S-shaped flow path, thereby preventing the nebulized medication from directly impacting and injuring the eye. In addition, due to the altered and curved flow path, the nebulized medication would diffuse around the rim of the eye cup, thereby covering a wider treatment area around the eye. The eye nebulizer therefore achieves an enhanced treatment effect and a greater applicability.
